The House of Savoy-Carignano (Italian: Savoia-Carignano; French: Savoie-Carignan) originated as a cadet branch of the House of Savoy. It was founded by Thomas Francis of Savoy, Prince of Carignano (1596–1656), an Italian military commander who was the fifth son of Charles Emmanuel I, Duke of Savoy. His descendants were accepted as princes étrangers at the court of France, where some held prominent positions. They eventually came to reign as kings of Sardinia from 1831 to 1861, and as kings of Italy from 1861 until the dynasty's deposition in 1946. The Savoy-Carignano family also, briefly, supplied a king each to Spain and Croatia, as well as queens consort to Bulgaria and Portugal.
